I've already been complemented twice on my previous answer, but then I discovered that I mis-read the question. My entire original answer was wrong, and I have to delete it.
I don't believe that any number can satisfy both of those conditions.
I'll say the question has no answer.
Answer:
550-554
Step-by-step explanation:
550 is rounded to 550, and also rounded to 600. Same with all the other numbers. :)
4 hours? i may be wrong
i did - 60 * 15
seems about right, since 50% would be 7.5 hours?
There is no decimal place
9/100 = x/90
Cross multiply to get 810 = 100x
Divide both sides by 100 to get x = 81 inches
